So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wang, Shu-Ju; Zhang, Zhi-Qing; Jiang, Yi-Hui; Xiong, Gang; You, Li-Xin; Ding, Fu; Dragutan, Ileana; Dragutan, Valerian; Sun, Ya-Guang researched the compound: 1,10-Phenanthroline( cas:66-71-7 ).Name: 1,10-Phenanthroline.They published the article 《Versatile monometallic coordination polymers constructed from 4,4′-thiobis(methylene)bibenzoic acid and 1,10-phenanthroline. Synthesis, structure, magnetic and luminescence properties》 about this compound( cas:66-71-7 ) in Inorganica Chimica Acta. Keywords: preparation monometallic transition metal thiobismethylenebibenzoate phenanthroline coordination polymeric complex; crystal structure transition metal thiobismethylenebibenzoate phenanthroline coordination polymeric complex; thermal decomposition transition metal thiobismethylenebibenzoate phenanthroline coordination polymeric complex; fluorescence transition metal thiobismethylenebibenzoate phenanthroline coordination polymeric complex; magnetic property transition metal thiobismethylenebibenzoate phenanthroline coordination polymeric complex. We’ll tell you more about this compound (cas:66-71-7).
Four novel mononuclear coordination polymers [Co(tmba)(phen)(H2O)0.5]n (1), [Mn(tmba)(phen)]n (2), [Zn(tmba)(phen)]n (3) and [Cd(tmba)(phen)(H2O)]n (4), H2tmba = 4,4′-thiobis(methylene)bibenzoic acid, phen = 1,10-phenanthroline, were synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction, powder X-ray diffraction, IR spectroscopy, and TGA. Single crystal X-ray diffraction showed that compounds 1, 3 and 4 build 1D chains whereas complex 2 displays a 2D layer configuration. Magnetic susceptibility measurements indicate that compound 1 exhibits the coexistence of spin-orbit coupling and antiferromagnetic interaction in the binuclear Co(II) center. Compound 2 manifests an antiferromagnetic interaction within the Mn(II)-carboxyl chain. Moreover, based on the solid state emission spectra of compounds 3 and 4, and of H2tmba and phen, relevant fluorescence properties were studied.
As far as I know, this compound(66-71-7)Name: 1,10-Phenanthroline can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
